WINDOW-FRAME.

Speccation of Letters Patent.

Yatented Sept. i6, i99.

Application filed February 14, 1919. Serial No. 277,007.

To all whom t may concern:

Be it known that I, HARRY S. DAVIS, a citizen of the United States, residing at Indianapolis, Marion county, and State of Indiana, have invented and discovered certain new and useful Improvements in Window- Frames, of which the following is a specification.

My invention consists of an improved construction of weather strips for window sash, .whereby the joint between the sliding sash and the window frame is completely closed againstI the passage of any air or dirt, and also whereby the use ot a strip separating the ways in which the upper and lower sash slide, and also molding at the sides of the sash,are.avoided, all as will be hereinafter more fully described and claimed.

Referring to the accompanying drawing, which is made a part hereof, and on which similar reference characters indicate similar parts,

Figure l is a cross section through one side of a window frame and sash, mounted with my improved weather strip, and illustrating its construction, and

Figs. 2 and 3 detail views showing the form of the parts more clearly.

In said drawing the portions marked A represent the part of the window 'rame against which the sash usually run in operation; B the lower sash and C the upper sash ot the window.

All of the above mentioned parts are or may be ot any approved or approi riate construction and require no special escription herein.

My improved weather strip 10 consists oi? a metal plate adapted to extend from the top to the bottom'of the part A of the frame, covering the outside half or" the face thereof, and is formed with two vertical beads Il and l2 united by a web 13, which beads also entend substantially from the top to the bottom of the frame. On the adjacent corners of the respective sash B and are mounted metal strips or plates le and l5 formed with grooves which correspond in form, in crosssection, to the shape of the beads 11 and I2 and are adapted to lit over said beads run thereon. Said parts 'iliand l5 are set into the adjacent corners oi the respective sash, as shown. rEhe web i3 is of a length to space the beads il and l2 apart that distance required to permit the *free movement of the sash by each other in operation up and down. In other words it spaces the sash apart in the same manner as the usual strip which is secured to the frame between such sash. 'These interlocking beads and grooves formed of metal, one secured to the frame and the other to the sash, form a rigid support for the sash in a vertical direction and also completelyv close the joint between the sash and frame, thus serving perfectly the purposes of a weather strip and in addition avoid the necessity and expense of the moldings usually used on both the outside and the inside of the frame against'the sash as well as the strip usually employed between the sash. y

The plate l0 covers the outside 'tace or the jamb and vthus protects it from the weather, prolonging the durability of the structure. In the drawing these parts are shown as somewhat separated from each other, the distance of separation being exaggerated in order to illustrate the construction more clearly. It will be understood that the parts are so itted that they run freely, but with no unnecessary space between them. An-

other advantage obtained by the` invention is that it dispenses wih the necessity of a molding, or holding strip, on the inside ot the window frame, leaving the closure to the pocket for access to the sash weights accessible by merely raising the lower window sash to above said pocket. These and various other advantages, as material saving of eX- pense, will readily sugvest themselves to the user.

I-Iaving thus i'ully described my said invention, what I claim as new and desire to secure by Letters Patent is:

l. A weather strip compiising a sheet of resilient metal provided with a portion having oppositely directed spaced beads, a second portion integral therewith adapted to be permanently attached to a window frame and tondino' to hold the beads spaced yieldj.

ingly away from the trarne position, and other independent strips provided each with a marginal curvature complementary and proportioned to slidably embrace one of the beads and to be attached respectively to ank upper and a lower sash.

2. A weather strip comprising a sheet of resilient metal provided with a portion having spaced beads, a second portion integral therewith adapted to be permanently attached to a window frame and tending to hold the beads spaced yieldingly away from lll() the frame position and other strips provided Iny hand and seal at Indianapolis, Indiana, each with a marginal' curvature complethis 27th day of January, A. D. nineteen mentary and proportioned to slidably einhundred and nineteen.

brace one of the beads and to be attached HARRY S. DAVIS. [L. s] 5 respectively to an upper and a lower sash Witnesses:
